Hello all,<br><br>I posted this question on <a href="http://at91.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">at91.com</a>, but have received no response, so I though I'd try here. I'm attempting to build a modified version of U-boot
v1.2.0 and am coming across a problem during the link stage. I used Buildroot to create my toolchain with GCC v4.1.2, uClibc v0.98.2, and Linux v2.6.20. I'm using a version of the U-Boot source patched specifically for the Atmel AT91 chips (can be downloaded at
<a href="http://www.at91.com/Project/Controleurs/cVisualisation.php">http://www.at91.com/Project/Controleurs/cVisualisation.php</a>). When I make all, I get the following error:<br><br>arm-linux-ld: ERROR: /home/alex/dev/ARM/Linux/sw/bsp/rootfs/buildroot/build_arm/staging_dir/lib/gcc/arm-linux-uclibc/4.1.2/libgcc.a(_udivdi3.o) uses hardware FP, whereas u-boot uses software FP

I'd like to be able to use the same toolchain to build U-Boot as I use to build Linux, but if that's not possible, any solution at all would be greatly appreciated.
